Participating assets are deployed via Flexitricity’s control room to either increase generation or reduce demand, when National Grid needs reserve energy to help them respond to any unexpected mismatch in supply and demand.
STOR is suitable for a wide variety of assets, and Flexitricity has the portfolio needed to choose the best commercial approach for each.
- Combined heat and power (CHP) engines and heat pumps;
- Standby generators (abated if required under the MCPD regulations); and
- Flexible load (lighting, industrial processes, HVAC, refrigeration, etc.).
Sites are paid for delivered energy (utilisation), and depending on the contract type, may also be paid for being ready to respond to a STOR event (availability).
Note: fast-responding assets like batteries can participate in STOR; however, they can earn more revenue from providing frequency response, or trading in the wholesale markets and the Balancing Mechanism.
